IMPROVEMENT IN rt-is MANUFACTURE OF 'SOAP.

To all whom it may concern:

Be it'known that I, B-A'LPH GROW, of Galesburg, in the county of Knox and State of Illi nois, have made a new and useful Improvement in the Manufacture of Soap; and-I do hereby declare that the following is a full and exact description thereof and of the process of manufacturing and compounding the same.

I would here state that the hydrocarbons which I intend to use, for the manufacture of my improved soap, and which I designate in this my specification under the general term naphtha, are the light oils or oils of distillation from petroleum and coal-oil, such light or distilledoils being cheaper for 'my purpose tnan either benzole, for which I have a patcut, or petroleum, and such light oils I here designate under the-term "uaphtha and desire to claim, whether they be produced by a single distillation or be 'redistilled. h

1n themanufacture of toilet-soaps the main objectis', first,'to produce an article which, while it is of a desirable quality, shall at the same time be afforded at a cheap rate to the consumer, and, seeond,-which can be used either for toilet purposes or for ordinary household washing. To'thisend'I have ascertained that by the simple combination of-"naphtha. with the common soft or hard soap an article is produced which when perfumedwill answer all the requirements 'ot'v the household; that while ,its penetrating qualities are such as to remove grease,varnish,paints, and spots from cloth, it acts upon theskin of the person 'using it in the most desirable .lnanner, leaving-the surface soft and without liability to ch'afe or chap. While not confining-myself to any particular proportions, I would state thatthirty ponnds'of common soft or hard soap added to one gallon of naphtha, as I shall describe, will produce the soap in question. The soft soap (or any other fluid soap) or hard soap is first taken and thoroughly dissolved in a proper vessel over a slow fire-say thirty pounds. One gallon of naphtha is then added and the 'whole stirred until thoroughly mixed. The

compound is then poured into molds'sto cool, after which it is fit for use. The naphtha may be added to the soap before subjecting the compound to the action of heat; but in either case care should be taken to cause a thorough union of the ingredients. When intended for toilet purposes the soap may be perfumed in the usual way. By the simple combination of the above named ingredients I produce in every'desirable respect a soap adapted to household p'ur-.

poses, and which can be afforded at achea-pe'r rate than any other soap with which I am ac-- quainted.

' To theingredients above named others might,

be added-such as ammonia, turpentine, camw pheue, coahtar, sal-soda, spirits of wine, gumcamphor, olive-oil, alcohol, rosin, marble-dust, kaolin-in varying proportions;- but all these I discard as unnecessary, either separately or in combination, and as adding a useless expense in the manufacture of my soap.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-' Y The use of hydrocarbons in the'manner and for the purpose substantially as described.

RALPH GROW.
